Aston Villa scored a late equaliser against the run of play to disrupt Chelsea's start to the Women's Super League campaign.
Sonia Bompastor's side were in complete control at Stamford Bridge, having taken an early lead through Lauren James.
They had plenty of opportunities in the second half to increase their tally, with Keira Walsh striking the underside of the crossbar and Aggie Beever-Jones having a goal ruled out for offside.
Lucy Bronze, wearing the captain's armband, also drew a smart save from Villa goalkeeper Akane Okuma before Sjoeke Nusken and Ellie Carpenter went close.
Although new Villa signing Amalie Vangsgaard fired inches wide, it was an otherwise uninspiring display for the visitors until Noelle Maritz scrambled a shot inside Chelsea's penalty area that bounced off keeper Hannah Hampton and defender Veerle Buurman and into the net.
Villa manager Natalia Arroyo jumped up in celebration, while Chelsea fans watched in disbelief and frustration after their side's missed chances.
It was a costly two points lost for Chelsea and a valuable draw to kickstart Villa's season.
